"Switzerland" ist ein (etwas umständlich zu bedienendes) von der US-Bürgerrechtsorganisation Electronic Frontier Foundation entwickeltes Tool, um rauszufinden, ob jemand unterwegs an den Datenpaketen rumgeschräubelt hat, die Dein Rechner mit anderen Rechnern austauscht.

Switzerland is designed to detect the modification or injection of packets of data traveling over IP networks, including those introduced by anti-P2P tools from Sandvine (widely believed to be used by Comcast to interfere with BitTorrent uploads) and AudibleMagic, advertising injection systems like FairEagle, censorship systems like the Great Firewall of China, and other systems that we don't know about yet.
